| Normal hydrophilic aluminum foil | High corrosion of hydrophilic aluminium foil | |
| Advantages | 1. Very good finishing, high thermal conductivity, good drawability and low density. 2. Collars height up to 12mm could be obtained(depending of the thickness and haracteristics of metal). 3. Studies performed by specialized in independent organisms demonstrate that does not favor the growth of micro-organisms. 4. With high hydrophilic preperties its is the best choosing for standard environments. 5. It is also possible to incorporate our pre-treatment systems that improve the protection against corrosion and the lacquer adherence over the aluminium surface. |
1. The polymers with high degree of reticulation aluminium lining prevent aggressive agents come in touch with the metal, they themselves being ver resistant to corrosion, the fins are at least 300% more resistant to corrosion than bare aluminum. 2. Very good finishing, high thermal conductivity, good drawability and low density. 3. Collars height up to 12mm could be obtained. 4. Finishing have been developed to have highest possible resistance to scratches. 5. Studies performed by specialized independent organisms demonstrate that this foil does not favour the growth of micro organisms. 6. It is also possible to incorporate our pre-treatment systems that improve the protection against corrosion and the lacquer adherence over the aluminium surface. |
